1 Claim. 01. 100-96) This invention relates to a mechanism whose functions are particularly adaptable for a combination fruit and vegetable comminuting and juice extracting machine, bymeans of which, as a particular embodiment, this invention will here be disclosed. More generally, this invention concerns itself with a mechanism including a slidably mounted member having a rest position, and a revolving shaft, where, when said shaft rotates in one direction, said member will move in one direction away from its restv position. When the shaft'rotates in the opposite direction, said member will be'return'ed' to its rest position and remain there during continuance of rotation of the shaft in suchreverse direction. Also, when said member is in its rest position,

and the shaft is rotated in such reverse dlrection, said member will not move.

An object of this invention is to provide a novel and improved mechanism of the character described in a machine for the uses mentioned, where rotation of the shaft operates a fruit and vegetable comminutor and-movement of the slidable member operates a juice extractor means.

Another object of the present invention is to provide a novel and improved machine for comminuting fruits and vegetables by a cutting, shredding or grating means or the like, and then by a simple manipulation, to actuate a press device for extracting the juice from the triturated material. 7

Another object hereof is to provide anovel and improved mechanism and its embodiment in the machine mentioned, which is simple to operate, -reasonably cheap in construction and efiicientin carrying out the" purposes for which it is designed.

Other objects, purposes and advantages will become apparent as this disclosure proceeds.

In the accompanying drawings forming part of this specification, similar characters of reference indicate corresponding parts in all the views.

Fig. l is a central, sectional side view of a combination comminuting and juice extracting machine embodying the teachings of this invention.

Fig. 2 is a section taken at lines 2-2 in Fig. 1, which is a fragmentary, sectional front view of said machine. Here, the slidable member of the mechanism mentioned, which member operates the juice extraction press, is shown in normal- 2 shown moved, from its normal rest, position, whereby the piston has been moved into the press cylinder.

Fig. 4 is a top plan view of Fig. 1.

In the drawings, the embodiment illustrated, comprises a frame designated generally by the numeral I5, which carries an electric motor It, the direction of rotation of whose shaft'll, can be reversed by electro-switch means. This shaft 11, extends within a housing I8, wherein it carries a disc cutter I9, having teeth 20, on a face thereof, for comminuting action on fruits and vegetables fed into housing I8, through a hopper 2|. The resulting mash is collected in a receptacle, here shown as 22 generally. The housing I8 may be provided with teeth 23, to co-operate with teeth 20, for finer cutting action. The mash leaves the housing l8, through a delivery spout 24. 4

The motor shaft I! also carries a worm gear 25, which is in engagement with a gear wheel or nut 26, journalled in frame l5. Said wheel 26 is interiorly threaded, adapted for engagement with v the screw portion 21, of a ram rod 28, positioned through such threaded bore in saidwheel. Said ram rod 28 has av portion 28', which is slidable through the threaded bore of the wheel, and extends from the frame I5, for action against a piston 29, slidably .fltted in receptacle 22; said frame having a suitable bed or platform portion 30, on which receptacle 22 'may be rested against a stop component 3|. The numeral 32 indicates a perforated cap which is detachably mounted onto either end of a receptacle made by tubular member 22 and its piston 29. The numeral 3| indicates apart of the frame I5, which serves as a stop for receptacle 22, and 35 is a juice delivery spout. The ram rod 28 is maintained against axial rotation by means of a key I 0 fixed on the frame and extending into a longitudinal groove 31 along said rod 28. The numeral 38 is a compression coilspring, fixed to the frame, but acted on to be stressed when the ram rod 28 nears the junction of its threaded and unthreaded portions.

It is advisable to have the springs 38 act against a plate or disc 39, which is freely slidable in the end portion of casing 40, which is of enlarged bore.

The manner of use and operation of this machine will now be explained.

During use of the cutter disc IS, the motor shaft I1 is revolving in such direction that screw 21, if in engagement with the threads 26' of the wheel 25, and the ram rod 28 will move towards the left in Fig. 2, until said screw is clear of the threads 26', whereupon said ram rod 28 will be in normal rest position, and spring 38, will be stressed. Cap 32 is off receptacle 22, and the latter is used to collect therein, mash issuing from delivery spout 24.

When the receptacle is filled, cap 32 is mounted on its open end, and the receptacle 22 laid on the rest 30,, so that it. isupagainst stop 3!, and piston 29. is opposite the head 39 of the-mam rod 28. Now the direction of rotation of shaft H is reversed. Stressed spring 38 will cause the engagement of screw 21 with threads 26 of the wheel 26. Rotation of said wheeliwhich is now" the cylinder or tubular member 22 towardslthe' cap 32, causing all juice contained in the mashwithin member 22, to be squeezed or pressed out. Such juice Will issue forth from the spout 35-to be collected in any'suitablecontainerfor use. A proper marking; not shown; on the ram rod 28, will indicate to the operator to stop or reverse the motor I85 Upon such reversal; ram rod 28 will be caused to ni'oVeoht-of'thecylinder 22', and will continue on-untilscrew portion 21 is out of engagement" with threads 25" of the wheel 26; whereupon said ram rod will cease'its movement, although motor l fi 'will continue with its shaft IT revolving'in such reversed'direction. Near'the end of the withdrawal of the'ram rod 28;- the spring 38 will againbestressed; readyto function upon reversalo'f rotation of the' motor shaft l1.

Portion 23 oftheram rod-2 B, is preferably a smooth rod, of'a diameter'sufiicient to clear the threads of wheel 26% Saidwheelmay' be-deem'ed a nut; adapted for threaded engagement with the screw portion 21 of the ram rod 28; in the particular mode of operation herein set forth.

It is evident that whenthe embodiment is such thatram rod 28 is positioned upright" or at'such slant that the action ofgravity'shall cause it to fall along its longitudinal axis; the spring'38 may be omitted; of course, the screw portion 21 of said ram rod, being-up'p;ermost. It is therefore desired that in the definitionof'themeans to accomplish the'functionof said1sprin'g .'38, tlie action of gravity shall be'd'eemed'its equivalent and included in such" definition.

This-invention is capable of. numerous forms and various applications without departing" from the essential features herein disclosed; It is therefore intended and desired that the particular embodiment illustrated herein be deemed,

illustrative and. not restrictive andthat the patent 4 shall cover all patentable novelty herein set forth; reference being had to the following claim rather than to the specific description herein to indicate the scope of this invention.

I claim:

In combination, a frame, a nut having a threaded bore and journalled on the frame whereby it is revolvable about the axis of its threadedebore, a screw adapted for threaded engagement withthe nut and positioned in alignment with the bore of the nut, co-operating means on the screw and frame to maintain the screw against axial rotation but permitting longitudinal movement of the screw, means to urge the screw longitudinally towards the nut when thescrew and nut are in disengagement, whereby the end of the screw thread nearest the nut is incontact -with the end of the threaded bore of the-nut, and upon rotation of the nut in one direction, the nut willthreadedly engage the screw and move the latter therethrough in one direction; and'upon reversal of the direction of rotation :of the nut, the screw; will move through the nutin the reverse direction until it :becomes threadedlydisengagedfrom' the'nut; the screw assuming'a substantially constant position with respect to" the" frame upon" such disengagement regardless of continued rotation of thenut in m such reverse direction,- means to rotate the nut comprising a driVingJshaft whose direction of rotation determines the direction of rotation of thenut, said shaft being" mounted on the frame, a comminuting means for" substances having juice therein which is driven by said shaft, and a" juice extractin pressicomprising' a cylinder havinga' piston; slidably positioned therein, the screw upon movement thereofin one direction through the nut, bein'gadapted'to move the piston into the cylinder; and means on the frame to maintain the cylinder"againstmovement in the direction'of the screw movement.
